IF-4P: IFC (Interferential) Traditional (4 Pole)
Interferential Current is a medium frequency waveform distributed
through two channels (four electrodes)*. The currents cross each
other in the body at the area requiring treatment. The two currents
interfere with each other at this crossing point, resulting in a
modulation of the intensity (the current intensity increases and
decreases at a regular frequency).
PARAMETERS:
Carrier
Frequency
Carrier frequency is the base frequency
of the alternating current.
Beat Frequency
(High & Low)
Occurs when two waveforms are in and out
of phases. The difference between the two
frequencies produces the modulated effect
(i.e. Beat H. of 4000 and Beat L. of 4150 will
yield a 150 pps beat frequency).
Vector-Auto
Vector-Auto is a form of
amplitude
modulation and
is a percentage of the set interferential amplitude
(intensity) and will decrease from its maximum level
over 6 seconds.
Vector-Manual
Vector-Manual is a form of
amplitude
modulation.
When Vector-Manual is set to a different angle,
the output intensities of two channels are different.
The rhythmical change in position of the
interference pattern, results in the modulation of
the amplitude of one or both input currents.
